' Patented May 23, 1916.

Application filed September 15,1914.. Serial No. 861,851.

To all whom it may concern. f

Be it known that I, WESLE QLARK, a citizen of the United States,reslding at Loveland, in the county of Larimer [and State of Colorado,have invented certain neW and useful Improvements in Road-Graders,

of which the following is a specification.

My invention relates to new and useful improvements in road graders andhas for its primary object the provision of a device of this characterwhich may be adjusted for various types of work.

A further object is the provision of means for holding the varioussections in their adjusted positions.

Vith these and other objects in view the invention consists in the noveldetails of construction and arrangement of parts which will be moreclearly understood from the following description and drawings, inwhich,

Figure 1 is a plan view. Fig. 2 is a longitudinal sectional view on theline 2-2 of Fig. 1. Fig. 3 is a longitudinal sectional view with thecenter point raised, and Fig. 4 is a transverse sectional view on theline 4-4 of Fig. 1.

In the drawings, I have shown the grader consisting of two sectionsindicated gen erally by the letters A and B, but it. will be understoodthat any desired number of sections may be used without departing fromthe spirit of the invention and adapting the device for use on roads ofdifferent widths.

The section A comprises a front plate 1 having the scraper plate 2secured to the bottom edge thereof, and the rear plate 3. the two platesbeing connected by means of the angle iron strips 4 and 5. Thesection Bcomprises the front plate 6 having the scraper plate 7 secured to thebottom thereof and the rear plate 8 connected to the front plate bymeans of the angle iron strips 9 and 10.

The sections are connected by means of the hinge 11, said hinge beingpivotally connected at the bottom of each section by the pins 12 andadjustably connected toward the top of the sections by means of theremovable pins 13 which enter the perforations 14 formed in the plates 1and 6 of the sections. A bar 15 is secured to the angle iron bar 9 ofthe section B and at the outer end is provided with a plurality ofperforations 16. The end of this bar is curvedas is clearly shown inFig. 1 of the draw- ,the angle iron connecting bar 5.

ing's and passes through a slot formed in the {angle iron" connectingbar 5 of the section A. fA removable pin 17 is adapted to entertheperforations inthe bar 15 andengages As is more clearly shown in Fig.1 the ends of the rear plates 3 and 8, respectively, of the sections Aand B are bent at right angles to form the abutting ends 18. Eye bolts19 and 20 are provided on the sections A and B, respectively, forattaching the traction power of any character.

Having fully described the detailed construction of my device it isthought that the operation will be clear. It will be noted that I haveprovided a grader which is adapted for both horizontal and verticaladjustment whereby it maybe used as a drag for merely leveling the roador for surfacing the road insuch a manner that it will be higherin thecenter than at the sides. When it is desired to horizontally adjust thesections the pin 17 may be removed from the perforations16 in which itmay be found and placed in any of the other perforations for adjustingthe sections to the desired degree. When it is desired to elevate thecenter of the grader for forming the road higher in the center than atthe sides the pins 18 are removed and adjusted in any of the Qperforations 14 to secure the desired elevation.

Having fully described my invention what I claim as new and desire tosecure by Letters Patent is 1. A road grader comprising two scrapingsections, a hinge between said sections to permit horizontal angularadjustment" betweenthe latter, a fixedliorizontal pivotal connectionbetween the bottom of the hinge and each section, and an adjustableconnection between the top of the hinge and said sections .to permitvertical angular adjustment between the same.

2. A road grader comprising two scraping 3. A road grader comprising twoscraping sections, a hinge connecting said sections to permit horizontalangular adjustment between the latter, a sector plate on one of saidsections movable through a slot in a portion of the frame of the othersection, a pin ofsaidsections, and removable pins adapted 1,1ss,954 v Ito be inserted in holes inthe upper end of mark Witnesses:
